RGEN is a library consisting of random number generator and data accumulation classes. Its envisioned purpose is in the development of Monte Carlo simulations where the ability to readily substitute a variety of random generators may be used to assess the influence of the underlying random number sequence on the simulation results.
The rh-isdn package consists of a few scripts and documentation to set up ISDN on Red Hat Linux, written with a little bit of inspiration by isdn4net and the SuSE-startup-files. The scripts have been tested with Red Hat 5.2/6.0 in combination with PAP-PPP, dynamic IP and an Elsa QuikStep 1000 ISA-card (only hisax is supported by these scripts right now, others should work with minor changes). This package is not intended for external modems or Raw-IP.
Rio (RAM I/O) for FreeBSD is an implementation of the Rio file cache project at Michigan. The basic idea of Rio is to make memory as safe as disk from operating system crashes. Such "reliable main memory" is useful in a variety of contexts, e.g. file systems, transaction systems, or checkpointing.
